REFRIGERATOR,

. Patented June 2'7, 1911.

Application filed October 25, 1910. Serial No. 589,019.

Be itknown that we, TURNER M. LAW- WRENGE and FRANK SNADON, citizens of the.

\ -UI,1itedStates-, residing at Nashville-in the "'i-haveinvented certain new and useful 1111- "that type of'refrigerators in which means county of Davidson and State of Tennessee,

provements in Refrigerators, of which the ffollowing'isa specification.

Our lnvention relates to improvements 1H.

refrigerators, and hasparticular reference to ;-1 A. are provided for weighing the ice as it is placedtherema" i The leading object of our invention is the 1 provision of a refrigerator Having an int I proved ice supporting pan so constructed and secured n position as to insure a thorough circulation of air in the refrigerator and cause said air in its passage to contact with: the entire surface of the ice to attain the maximum chilling eflici ency thereof. l A further object of the invention is the provisioniin connection with the lee pan of improved means for supporting the same in position, which means are connected with an indicating scale on the face of the refrigerator to indicate-the weight of the ice as it is placed in the refrigerator and thus to prevent shortweight and cheating on :the part of the ice man.

Another object of the invention is. the provision of improved means which can be readily secured to the interior of any ordinary refrigerator for supporting the ice pan thereof, which means will support said pan in. the central portion of the refrigerator to" provide a circulation space entirely therearound.

To. attain the desired objects, our inven-' the ice pan and supports in the interior of.

the refrigerator. Fig. 3 represents a top Fig. 2 represents a verticalplan view of the supports or hangers for the ice pan, the pan being removed. Fig. 4 represents a perspective view of the icepan with one of the ends therefor in position to be attached thereto. Fig. 5 represents an enlarged side elevation of the supporting bracket and bearing link, and, Fig. 6 represents an enlarged detailed view of the in-- dicator controlling mechanism.

v In thedrawings, in which similar characters of reference are employed to denotecorresponding parts in the several views, the numeral 1 designates the base of the refrigerator, 2 the sides, 3 the top and 4 the front thereof, said partslbeing of ordinary construction and forming no part of my in vention, while secured on the face of the re frigerator is a dial 5 having an indicator 6 mounted on the shaft 7 which extends into the interior of the refrigerator.

Secured to the sides 2 at their upper portion near each corner of the refrigerator are the brackets 8 having flanged bases 9 secured to said sides, and each of said brackets is provided with the knife-edge bearing 10 on wvhich is mounted the double loop link 11,

as shown in detail in Fig. 5. Engaged in the lower loop of said link is the double knife-bearing 12 formed on the lever 13, said lever having a similar bearing 14: formed on the other end but on the opposite side to the bearing 12, while engaging the bearing l t to support the free .end of the lever 13 is the loop 15 of the rod or connection 16, said connection being provided at its upper end with a second loop 17.

Secured to the inner face of the front of the refrigerator by the brackets 18 which slidably retain the same is the rod 19 bearing the rack 20, a cross-bar 21 being secured to the rod and having at each end the knifebearing 22 for engaging the loop 17 to sup'-. port the lever 13 on each'side, as shown in Fig. 2. The-rack portion 20 of the rod 19 theshaft 7, the shifting of the rod 19 thus serving to move the indicator 6, while a spring 24 is secured to the upper end of the rod and to the end of the set screw 25 prois in mesh with the pinion 23 mounted on jecting through the top, the adjustment of:

said screw serving to regulate the-tension of the spring. 1

From the foregoing description it will. be

seen that the 'levers' 13 being supported throughout on the knife hearings will swing with a -minimum frictional resistance and that any weight bearing on said levers will swing the same on the brackets as fixed pivots and will consequently depress their inner end, drawing down upon the rod 19 against the force of the spring 2st and thus moving the indicator around its dial on the front of the refrigerator.

While it will be understood that the ice container may be supportedin any desired manner from the levers l3 and the weight thereof indicated on the dial, we prefer in this connection to employ our improved ice pan, said pan comprising atray 26 having on the under side the ba'tlle or guiding rib 27 and having downwardly bent flanged ends 28, said ends 28 making interlocking engagement with the upturned ends 29 of theend members 30. The members 30 have tongues 31 cut from their edges and bent downward, said tongues engaging over knife-bearings or lugs 32 which project inward from the levers 13, the said ends and thus the pan being supported by the levers and depressing the same when the pan is filled. The pan is preferably provided with a drain spout 33 for leading away the water from the melted icc, said spoutdischarging into the drain pipe 3%.

From the foregoing description taken especially in connection with Fig. 2 the operation of our improved refrigerator will be readily understood and it will be seen that the pan is supported in the refrigerator away from the sides and ends thereof, the warmer air at.the bottom of the refrigerator passing upward along the sides and a portion passing between the ends of the pan and the side wall, while the rest contacts with the chilled bottom of the pan and passes therealong until it strikes the batlie plate which throws it downward toward the center of the refrigerator, thus providing two whirls or circulating currents, the air from the ice passing down at the sides of the pan and commingling with the air there circulating.

The advantages of this construction will be evident to all and it, will be seen that we have provided a simple but highly eiiicient combined refrigerator and ice weigher which can be installed by any, one, it being necessary merely to secure in position the four corner brackets and then hang the levers and other parts therefrom, thus providing a refrigerator in which the air. will circulate more rapidly and be maintained at a lower temperature than with the ordinary type of refrigerator int common use, while the weighing attachme at prevents cheating on the part of the ice! man and enables a person at all times to know exactly how much ice is in the refrigerator without opening and peering into the same.

We claim 1. The combination with a refrigerator, of a pair of levers swingingly mounted in the refrigerator, an ice pan mounted upon the levers, and a weighing and indicating mechanism operated by said levers, and consisting of a pair of links connected to the inner ends of the levers, a vertically movable rod connected to said links, an indicator operated by the said rod and a spring connected to the rod.

2. The combination with a refrigerator, a pair of levers each having an arm pivotally mounted in the refrigerator, an ice pan having tongues to engage the arms if said levers, a .pair of links connected to said levers, a spring controlled rod connected to said links and an indicator operated by said rod.

3. In a refrigerator, brackets secured thereto, levers having one end pivotally secured to the brackets, means for supporting the free ends of the levers, said levers having laterally projecting lugs, end members having tongues engaging said lugs, and an ice pan removably secured to said ends and supported thereby.

at. In a refrigerator, the combination with the sides, of brackets secured thereto provided with knife-bearings, double-link loops engaged on said bearings, levers having integral bearings on each end, the bearings on one end being engaged in the lower loop of the links, a rod having a rack formed thereon secured to the front 'of the refrigerator, connections between said rod and the bearings on the free end of the levers, an indicator operated by the rack, and an ice pan suspended from the levers and spaced from the sides of the refrigerator.

In testimony whereof we affix our signatures in presence of two witnesses.
